I really like the layout and button shapes in your design but the colors and contrast are horrible. You need to change the text to white or something otherwise if you get that in the car on a sunny day its going to look like a red blob on the screen.

ok peeps , i shall put a little more work into it. like you say its my first attempt so its gonna take a while to get it right, i must admit after being away from it for the night and comming back to look at it this morning it does look too red! think i just got carried away last night! lol
